SQUEEGEE F OR FLOORS.

Application filed May 8,

T 0 all whom z'tmay concern r Be it known that I, JAMES M. OBERTI, a citizen of the United States, residing at San Francisco, in the county'of San Francisco and State of California, have invented new and useful Improvements in Squeegees for Floors, of which the following is a specification. ,7 j.

- This invention relates to improvements in squeegees for mosaic, stone, monolithic and like floors and has particular reference to a simply constructed and highly effective squeegee which due to. its peculiar construction and arrangement will provide for a more eflicacious and thorough wiping and removing ofwater from floors.

The primary object of the invention is to provide a squeegee which when water is being pushed in front of it will prevent the water from flowing past the ends of the squeegee onto areas of the floor not being wiped and to also provide a squeegee which will at all times, regardless of how pressure is applied thereto through the handle or its movement over the floor maintain a firm and effective contact with the floor.

Another object of theinvention is to provide a squeegee which is curved in such manner that the water will be cupped in front of the squeegee whereby tilting of the handle will not, as in the case of the ordinary squeegee cause the rubber elements of the squeegee to be lifted from the floor.

A further object is to generally improve squeegees so as to simplify and render more effective the construction and operation thereof. j

The invention possesses other advantages and features some of which, with the fore going will be set forth at lengthin the following description where I; shall outline in full that form of the invention which I have selected for illustration in the drawings accompanying and forming a part of the present specification. In said drawings I have shown one form of the construction of my invention, but it is to be understood that I do not limit myself to such form since the invention as expressed in the claims may be embodied in a plurality of forms.

Referring to the drawings Figure 1 represents a top plan view of a squeegee constructed inaccordance with my invention,

1922. Serial no. 559,134.

Figure 2 represents a side elevationof a squeegee. i

Figure, 3 represents a front elevation of the squeegee.

Figure, 4 represents a fragmentary vend elevation taken at one end of the squeegee.

. Figure 5 represents a vertical sectional view taken through the center ofthe squeegee. r i j Referringto the embodiment ofthe' invention illustrated in the accompanying drawings, .1 and 2 designate metal bars which constitute the body portion of the squeegee, said bars having clamped between them arubber floor engaging strip 3. The bars 1 and 2 are clamped together so as to hold the rubber strip therebetween, by means of bolts 4 extending through the bars and held in place by nuts 5, the rubber element 3 being disposed with its upper edge in contact with the bolts. Each bar is reduced or formed of less height intermediate of its ends and gradually increased in height towards each end so that a greater projection of the rubber strip 3 is provided at the mediate portion of the squeegee and this projection diminishes gradually towards each end thereof. Since the ends of the squeegee are far removed from the point at which pressure applied to the handle is transmitted to thesqueegee, if the rubber element projected considerably at the ends, 7

it would have a tendency to lap under without firmly bearing or engaging upon the floor. By having the degree of projection or extension of the rubber element lessened from the center towards each end of the squeegee, the rubber element is made sufiiciently stiff to prevent its being folded under without properly contacting with the floor. I prefer to taper the under edges of the bars 1 and 2 to provide for this rather than out the rubber strip irregularly, said rubber strip being, as shown, substantially rectangular in form.

A Y-shaped bracket 6 is pivoted at its free ends to lugs 7 mounted at points to one side of central points upon the bars 1 and 2. The Y-shaped bracket includes as a body portion a handle socket 8, which is disposed opposite a point on the bars 1 and 2 central of the ends of said bars but above the latter. A suitable handle 9 is fitted into the socket 8. A pivoted handle attached to the medi-' ate-portion of the squeegee is 'necessaryto j i I 1,497,933

the successful operation of the squeegee, because if" the handle were rigidly attached and were pushed forwardly and upwardly from the operator, the ends of the squeegee would act as fulcrum points and cause the mediate portion of the squeegee to lift free of the floor. With the pivoted handle of my invention the squeegee is maintained in firm and proper contact" with the floor at all times re ardless of the disposition or movement 0 the handle in operating the squeegee over the floor and I consider this to be 'oneof the most essential features of my invention.

Due to the curving of the squeegee, the water pushed in front of the rubber element while moving the squeegee over the floor willbeheld within the area embraced the squeegee and will not run past the ends of tlie squeegee'into the; adjacent area's of e, the floor; In this way the removal of water from the'fioor may be eifect'e'd more quickly and easily than with Squeegees of the straight I claim:

1. A squeegee comprising a body portion curved from end to end, the lower edge of the body portion being cut away in concave form from end to end, a rubber floor engaging element secured to and having a curve corresponding to the body portion with its lower edge disposed in a horizontal plane, said element projecting to a greater extent from the body portion at a point intermediate the ends of the body portion and diminishing in its projection towards its'ends 2. A squeegee comprising a body portion curved from end to end the lower edge of the body portion being cutaway in concave form from end to end, a rubber floor engaging element secured to and having'a curve corresponding 'to the body portion with its lower edge disposed in a horizontal plane; said element projecting to a greater extent from the body portion at a point intermediatethe ends of the body portion and. diminishing in its projection towards its ends and a handle'pivotall'y connected witlith'e body portion. 4 ,i
